First off, the device I am running these on is the iStick 50 watt and for some reason both my Lemo 2 and my Silverplay V2 always seem to leak under the tank so every time I take the tank off of the iStick, there's always a round circle of e-juice, it's pretty annoying. I tried re wicking multiple times and still same thing. Anyone out there who experiences the same thing? Thanks so much
